title: Acute foot drop syndrome mimicking peroneal nerve injury: an atypical presentation of ischemic stroke.
abstract: Foot drop syndrome is a frequent neurologic condition usually caused by peroneal nerve damage. On rare occasions, foot drop may present as the single neurologic manifestation of intracranial lesions. We presented a 43-year-old man admitted to our hospital with acute weakness in the dorsiflexion of his right foot that appeared 3 days before admission. Brain magnetic resonance imaging diffusion-weighted sequence revealed a small area of restricted diffusion in the left frontal cortex. Three months later, his motor deficit had completely improved (modified Rankin scale score = 0). To our knowledge, this is the second report of sudden isolated foot drop caused by a cortical infarction.
